Indoor Real-time localization system design for Internet of Things applications

Pooneh Mohaghegh

With the prevalence of smartphones, watches, and Internet of Things (IoT) devices, the abilityto track their positions is becoming increasingly important. For many indoor positioningsystems (IPSs), providing an uninterrupted flow of information in real-tim ...

Implications of Position in Cryptography

Handan Kilinç Alper

In our daily lives, people or devices frequently need to learn their location for many reasons as some services depend on the absolute location or the proximity. The outcomes of positioning systems can have critical effects e.g., on military, emergency. Th ...

Secure Contactless Payment

Serge Vaudenay, Handan Kilinç Alper

A contactless payment lets a card holder execute payment without any interaction (e.g., entering PIN or signing) between the terminal and the card holder. Even though the security is the first priority in a payment system, the formal security model of cont ...

Security of Distance-Bounding: A Survey

Serge Vaudenay, Gildas Avoine, Martin Benjamin, Srdan Capkun, Aslan Tchamkerten

Distance-bounding protocols allow a verifier to both authenticate a prover and evaluate whether the latter is located in his vicinity. These protocols are of particular interest in contactless systems, e.g. electronic payment or access control systems, whi ...

Contactless Access Control Based on Distance Bounding

Serge Vaudenay

Contactless access control systems are critical for security but often vulnerable to relay attacks. In this paper, we define an integrated security and privacy model for access control using distance bounding (DB) which is the most robust solution to preve ...

Electrical and Magnetical Modeling of Inductive Coupled Power Transfer Systems

Christophe Bruno Auvigne

Nowadays, there is a very high number of electronic devices with different ranges of power. Desktop peripherals and cellphones are an example of widely used low power devices. Contactless power transfer is useful to supply or recharge these devices without ...

Design considerations for a contactless battery charger

Yves Perriard, Yoan René Cyrille Civet, Paolo Germano, Christophe Bruno Auvigne

Contactless power transfer using inductive coupling is a well-known way to transfer energy from a transmitter to a receiver without any physical link. The applications are multiple. In this paper, the design and control of such a system for a contactless b ...

Meshing strategy of equivalent substrate schematic in SMART power IC

Maher Kayal, Jean-Michel Sallese, Fabrizio Lo Conte

In this paper, a modeling methodology able to create an equivalent schematic of an High-Voltage integrated circuit is developed. The equivalent schematic is based on enhanced model of diodes and resistances, accounting for minority and majority carrier pro ...

Design of a contactless energy transfer system for desktop peripherals

Yves Perriard, Paolo Germano, Miroslav Markovic, Pascal Meyer

This paper presents an approach to design a contactless energy-transfer system to supply desktop computer peripherals. Energy is transferred using coreless transformers from an array of primary coils (placed on a table) to one or several secondary coils (p ...
